Go sail a 21 footer against a 70 footer and you will have your answer. The
longer the sailboat typically means a faster one.

The America's cup race over a hundred years ago ended in accusations and
disputes.Lord Dunraven accused the Am Defender of having carried illegal
ballast which would have extended her water line and consequently given
her
greater speed-(taken from the book)
My question is: How is that?
Would n't the extended water line be more serface area in contact with the
water, there by slowing the boat down. By having a greater resistance..But
is that different with sail boats?
